The densities of carbon dioxide, acetone and a mixture containing 57 mol % carbon dioxide that were measured at 306 bar and 323 K are reported as 0.8925 g/cm3 ; 0.7884 g/cm3; 0.8494 g/cm3, respectively.Using the Peng-Robinson equation of state calculate the densities of carbon dioxide, acetone, and the mixture with 57 mol % carbon dioxide at these P / T conditions, and compare with the experimental values given above.In determination of the PR-EOS parameters for the mixture, assume that the interaction parameterk12 = 0
